Well, who knew; even a broken watch is right two times a day :)
I've started to rummage through the openbsd-cvs mails, and searched for
a similar commit, and after 'viac3_rnd' didn't yield much result, the
next search, 'amd64_errata' was fruitful.
There were two commits back in March by jsg@, namely to
sys/arch/i386/i386/amd64errata.c(r1.3) and
sys/arch/i386/include/specialreg.h(r1.41) about some workaround for AMD.
Reverting these two little patches solved this issue on the i386 guest:
